eBPF programs as a linux kernel sandbox has runtime guaruntees and privileges make for good observability tools. Combined with containers, eBPF programs have interesting capabilities in modern infrastructure.

Really like what web assembly brings to the web. Add websockets and progressive web app (PWA) services, I can see a lot of potential.

A secure decentralized tech notably used in bitcoin amongst other things. Quite neat what netgineers have done with it. Notably cryptokitties (Flow) or Audius. Local vancouver decentralized club is pretty cool too.

The Linux namespace additions to the kernel have proved extremely useful. Containerization solutions like Docker, Podman, LXC, or Kata Containers make deployments and testing highly reproducible. As a lightweight alternative to virtual machines, they effectively reshaped the world of shared infrastructure.

Intrastructure as a service has a lot of interesting self-hosted options. It may cost you for a better VPS setup but you could probably run a lot more.

Keybase has a nice solution for managing encryption (can always access your PGP key). I personally yubikey for services that support it. Try to sign git commits on projects when I can.

An interesting area to be understandably excited about. The consumer/developer frameworks are simple and useful enough. The math and training new models is a bit complicated. I worry about security and the importance of data privacy.

Will probably get one at some point, it is the only mobile platform I have not worked on. They happen to make great secure laptops with open source hardware too.

React Native, Flutter and Xamarin are most interesting to me. A holy grail for developers to save development time and have a consistent user interface. There are trade offs like performance or lacking endless scrolling, however the native bridge is always there if necessary.

A penetration testing technique that is amazing at finding software bugs. Notably, the impressive trophy case of AFL.
